ff wh c t and an operating member, of change speed mechanism for transmitting motion from said member to the gear, said mechanism including an internal gear, a cage, and a train of gears in the cage and meshing with the internal gear, means under the control of the operator for shifting said cage to one position to reduce the speed of the driven gear, to another position to insure equal speed of said member and gear and to a third position to uncouple the drive connection between said member and gear, and means for securing said shifting means in one of its positions.

2, In a hand feed for drill presses a spindle actuating gear, an internal gear revoluble with said actuating gear, an operating member, a stationary cover plate, a shiftable cage surrounded by the internal gear, a train of gears movable with the cage and meshing with the internal gear, one gear of said train being revoluble with the operating member, means for shifting the cage, andmeans operated by the shifting of the cage for coupling said cage to the cover plate or to the internal gear.

In a hand feed for drill presses, aligning shafts, an operating member connected to one shaft, a power transmitting member connected to the other shaft, a disk revoluble with one of the shafts, a stationary cover plate, an internal gear carried by the disks, a cage interposed between the disk and cover plate, a train of gears carried by the cage and meshing with the internal gear, said train including a gear upon the shaft of the operating member,-coupling members carried by the cage, and means for shifting the cag in one direction to couple it to the cover plate, and in the opposite direction to couple it to the disk, said cage when in intermediate position being uncoupled from the plate and disk.

4. In a hand feed for drill presses, ali ing shafts, a power transmitting memfiir connected to one of the shafts, an operating and meshing with the internal gear, said train including a gear upon the shaft of the operating member, spring pressed coupling pins normally projected from opposite sides respectively of the cage, means under the control of the operator for shifting the cage to project the pins into engagement with the disk or with the stationary member.

5. A hand feed for drill presses including aligning shafts, a gear upon one shaft, an operating member on the other shaft, a disk revoluble with the gear shaft and having openings, an internal gear movabl with the disk, a stationary member having recesses, a vcage interposed between the sta tionary member and the disk, a train of gears movable with the cage and meshing at one end with the internal gear, said train including a gear upon the shaft of th operating member, spring pressed coupling pins slidable within the cageand normally projecting from opposite faces respectively of the cage, said stationary member having a cam slot therein, and means under the control of the operator and working inthe slot for shifting the cage to project the coupling pins into the openings in the disk or into the recesses in the stationary member, said cage being movable to an intermediate position with its pins uncoupled from both the disk and stationary member.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
